OneTraining Platform for Dissection, Inspection and Diagnosis of New Energy VehiclesIntroduction
This device converts a normally operating BAIC New Energy EV150 pure electric sedan (refurbished second-hand car) into an online detection teaching aid vehicle, which can real-time detect and diagnose the dynamic and static signal parameters of the original vehicle's combination instrument control unit, gateway control unit, P-speed motor control unit, motor control unit, gear control unit, on-board charger control unit, DC/DC control unit, high-voltage battery ECU control unit, etc.
Applicable to the teaching needs of various colleges and training institutions for the theoretical and maintenance training of pure electric cars.
The functions of the teaching platform include six major systems: drive transmission system, power battery and management system, electric power steering, air conditioning and heating system, electric vacuum power hydraulic braking system, and vehicle electrical system.
By dissecting the new energy vehicle, one can clearly see the structural structure of the cabin and body side panels, the thickness of the steel plates and independent suspension system, as well as the wheel hub of the new energy vehicle. This can display the positions of the main components and accessories of the vehicle. The main components of the new energy vehicle are dissected into two parts through special processing technology, making the internal process shape and structure of the components clearly presented. Through the dissection and demonstration of the new energy vehicle system, students can have a clear understanding of the internal structure and function of new energy vehicles, and quickly grasp the structure and principles of new energy vehicles, improving their preliminary understanding of the internal structure of new energy vehicles. Students can have a more intuitive understanding of power motors and electronic control systems, and can delve deeper into their studies. The layout of the equipment is based on the original structure of the car. On one side of the transparent decorative surface is the complete shape before disassembly, and on the other side is the internal shape of the car after disassembly. By comparing before and after disassembly, students can deepen their understanding and learning of the structure of new energy vehicles. The entire equipment not only has practical training functions, but also can quickly improve the learning atmosphere of new energy vehicle majors.
